WATER-SCREENING AZIPPABATUS.

' Specincation of :Letters Patent.

Appuation mea my 1a, 191s. serial m. 97,043.

To all 'whom t may concern Be it known that I, BENJAMIN S. REY- acitizen ofthe United States, residing at Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented certain new and useful'Improvements in Water-Screening Apparatus, of which the following is aspecification.

My invention has fory its object to improve water screening apparatus soas tol make it practically possible to use a comparatively short screenin situations where the water level varies greatly from time to time. r

.In the accompanying drawings I have illustrated a typical installation-of fiume screen embodying my improvements.

Referring to these,-Figure 1 is a vertical sectional view of theapparatus. Fig. 2 is a face view of the same. Fig. 3 is a horizontalsectional view on the line III--III of Fig. 1. y

In the drawings, 2 indicates a stream from which water. is taken, to bedelivered, through intake pipes or tubes 3, to an industrial plant.These pipes connect with a chamber 4 in which the screened water colledoff through the pipes'. The chamber 4 lies behind a dam or partition 5that separates it from the stream 2, and through this dam are formed aplurality`of-openings 6, one above the other, and each of a sizesufficiently large to .per-

i `mit the iow of a volume of water such as gaged by may be required bythe plant when working .at its maximum capacity. Fitting in each opening6, or covering them, are coarse stationary screens or gratings 7 adaptedto intercept the coarser bodies that may be carried by the water, suchas cakes of ice, pieces of wood, etc.

8 indicates an adjustable gate adapted to 'close the openings 6. It isrepresented as being supported by vertical guides 9 secured to the faceof the wall or partition 5. It is of a size to cover one of thelopenings 6, and, ,in the embodimentv of the invention illustrated, isarranged to be adjusted by hand, for which purpose a rod 10 is securedto the gate, this being screw-threaded throughout a portion of itslength and ena nut Vsuitably supported, and arranged to be turned by thehand wheel 11. It will be evident from an examination of the drawingsthat whenthe gate is adjusted to one position it uncovers one opening 6and closes the other.

On me side of the partition 5 opposite the gate 8 is arranged an endlessautomatically cleaned fiumescreen 12. This screen is preferably 'locatedwithin the collecting chamber 4. It consists of a supporting frame 13 inwhich are mounted lower and upper wheels, designated 14 and 15respectively, upon which are supported an endless screen formed ofarticulated sections 16. As stated, this form of screen is well known 1nthe art and need not, it is thought, be described more in detail.

The screen is power operated, being represented as driven from a motor16 through suitable gearing including belting 17 connected with theshaft carrying the upper set of screen supporting wheels 15. 'The screen12 is large enough to cover 'one of the openings 6 so as to interceptany coarse material carried by the water, and is held Patented July 11,1916'. Y

close to the face of the w'all or partition 5 Y by guides 18. n

The screen as a whole is vertically adjustable, so that it may bearranged in operative position opposite either of the openings 6. Topermit and facilitate this the guides 18 are vertically disposed andarranged to permit the screento be moved up and down along them, and`the screen is counterweighted as indicated at 19;. A hoisting cable 20is also connected with the screen frame, passing, in its course, oversheaves 21 mounted in a tower or framework 22 supported above the dam orpartition 5. The hoisting cable is wound upon-a drum 25 arranged .to bedriven in any suitable manner, as from the motor 16. y j

23, 24 indicate gutters for receiving the refuse removed or dischargedfrom the screen surface. The means for cleaning the screen of refuse arenot shown or described, Y

'as they are well known in the art and may be of any suitable kind.

In Fig. 1 the parts of the apparatus are i represented in position foroperating when the water is at a lowl stage or level, as represented ata. Under these conditions the lgate 8 is .elevated to close the upperopensuch vertical position that it will permit a flow of water` throughit ample in quantity to supply all the needs of the plant, even at thelowest water stage that may be expected to occur in the stream 2Q Whenthe parts lare thus arranged the water passes freely through the loweropening 6 and is cleansed by the screen 12, the refuse taken therefrombeing delivered tp and carried away throu h the lower gutter 23.v vThewater level in t e chamber 4 is supposed to be the same as that in thestream 2, since the opening 6 should be more than ample to supply theintake pipe or pipes 3, W discharging their full capacity. Should theWater in the stream rise the parts may remain in the positions justreferred to until the level indicated by the dotted line c is.

reached. When this occurs the refuse gutter 23 becomes flooded and thematerial discharged from the screen cannot be carried,

oil properly but would rather accumulate in the chamber 4 and hencebeliable to go to the apparatus of theplant through the 1ntake-p1pes`3.Whenever the water in the ,stream is above the level indicated by'thedotted line c, the parts are adjusted to occupy the positions indicatedin Fig. l by dotted lines; that is to say, the gate 8 is lowered touncover the upper opening 6 and close the lower opening, and the screenelevated so as to be in inoperative position opposite theruncoveredopening, that is, the

' upper one.` The water from the stream 2 is therefore cut-oil from thelower opening and is delivered through the upper opening,

and under theadjustment just referred to, the apparatus will operatesuccessfully until it reaches the maximum level indicated at b. When thewater is delivered from-'\the stream through Ithe upper opening therefuse is taken olf through the upper gutter 24 which isllocated at orabove the maximum Water level.

Should the apparatus be used for screening water taken from a stream inwhich the water level fluctuates more widely than that indicated in thedrawings, a greater number of openings 6, and of refuse gutters ordischarge means, should be provided. It is howeverv thought to beunnecessary,` for a full understanding of the invention, that anarrangement having more than two openings 6 be shown.

have illustrated th gate as being supported upon the opposite side ofthe partition 5 from the screen 12,. but, while this is the preferredarrangement, it is not essential to the operation of the apparatus norto my invention, as all that is required is that the gate shouldfbeadjustable so as to cut off the water from one or the 6, as may berequired.

It is evident from the foregoing description, taken in connection withthe accompanying drawings, that a fiume screen of comparatively smallsize, as to length, may

en the latter are other of the openingsvv the smaller appara-tus that isrequired, and y also a savin in running expenses, since the powerrequired to drive the lighter and smaller apparatus is not so great asthat requlred in arrangements vsuch as have heretofore `been employed.

It will be understood that the belting 17 is shortened whenever thescreen is adjusted to the higher position. I therefore refer to use forthis belting sprocket or otli of chain belt, the links of which may beeasily separated to permit either the removal vtherefrom or the additionthereto of sections, as may be required.
